Decor for Making My Furnished Living Room More Inviting?

Q: My husband and I live in Ethiopia. Consequently, decorating on a budget is not easy. We live in a rental and therefore are somewhat limited in what we can do. Not to mention, we moved with just a few suitcases and decorating items were not a priority. I need advice on how to make this room more inviting, and how to work with this red couch. I'll be in America for a bit this summer and will be able to use some resources there. Any suggestions?
